Hi,

I have built a plugin for Elastic and I also included CXF and JAXRS so that I could use the `org.apache.cxf.jaxrs.client.WebClient` like this:

```java
try {
    String responseString = AccessController.doPrivileged((PrivilegedAction<String>) ()
    -> {
        Response response = WebClient.create(url).
                accept(MediaType.APPLICATION_JSON).
                type(MediaType.APPLICATION_JSON).
                post(new Gson().toJson(request));
        return response.readEntity(String.class);
    });
 } catch (Exception e) { }

```

now, when plugin is running and I make a request I get the following stack trace:

```auto
[2019-01-03T11:08:11,816][ERROR][o.e.t.n.Netty4Utils] fatal error on the network layer

...

```

```

Here are some dependencies I used:

```auto
<dependency>
  <groupId>javax.ws.rs</groupId>
  <artifactId>javax.ws.rs-api</artifactId>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <exclusions>
    <exclusion>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
    </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-annotations</artifactId>
</dependency>

```

Any idea about the source of the issue?

Thanks a lot!

Ok I solved it by adding:

```auto
<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.2.11</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.2.11</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.2.11</version>
</dependency>
<dependency>
  <groupId>javax.activation</groupId>
  <artifactId>activation</artifactId>
  <version>1.1.1</version>
</dependency>

```

and removing:

```auto
<dependency>
  <groupId>javax.ws.rs</groupId>
  <artifactId>javax.ws.rs-api</artifactId>
</dependency>

```
